a maj/ concern.' l" it Known that l, HERMAN C. BLYE, a eitzizen of the United States, residing at Iniilianapolis. in die fonnty of Marion and citate of indiana. have invented a new and useful Internal Combustion Engine, of nhich the following a specification.

rl`he ohject of my invention is to produce improven'lents in the valve structure of an internal combustion engine of such character that a cylindriczl rotary valve may 'oe used: a gas-tiglit joint he nniintained there with at all `times and the valve cooled hy direct Contact with a Cooling stream of air fmced automatically th rough the port of the valvI at each half revolution thereof.

The accompanying drawings illustrate my invention Figure l is an axial section through one ci.' the cylinders of an engine equipped with .my impiwived valve; Figa'. 2 is a section on line T2-f2 of Fig. l: and Fig. 3 is a side eleration. with the packing rings removed, oi the {iexihie feat structure for a four-cyliml9r engine 'ln the drawingsl l() indicates a cylinder and il a enacting piston mounted in the cylinder The cylinder head comprises a cylinda-irai portion l2, equipped with packing rings lil. which fits the. cylinder, The cylinder head also `comprises a pair of oppo- "iti'ly extending arms 1T', l5, which form .seats for supportine,r springs 16. 1G, which normally urge the cylinder head upwardly, and the cylinder head provided in its upper face with a segmental valve scat 17 in which' the iigvliiu'lrical valvel 18 is adapted to rotate.

The valve 18 ma y be in several sections, as indicated in Fig. 2, there being one section tor each cylinder and each of these seci tions is provided with a single diametrical port 19. The valve structure may he made in several sections connected by tongifue-and- ,ogrliiove connections 2l, if desired, and is supported at its ends in i-aiital'iie hearings 22 married hy a casing which is mounted .upon the upper end of the cylinder structurn so as to incloso the. ryiinder head aldy described.

4ar-mit eaeh cylinder 10q easingl 23 is provided with two oppo site-ly extending passages Mr and which communicate with a dirafnwsrflly presented segnwntal seat QG which lies opposite the l? and reef-iv@ the valve 1S, The passirahle that the several cylinder head struc# ztcnted May 2, 1916.

sage 524 the exhaust passage and delivers to an exhaust manifold while the passage is an inlet passage and communicates with lhe )nel man il 2T.

The seat r3 ,ingularly spaced from the seat l? at each end a distance ly eater than Ithe angular extent of the port i9 so that the valve is exposed to the. contents of the two chambers 3l. 3l which are formed Within the easing- 23 and so that each of the ports lil is compelled twice in each rotation of the valve to form a direct connection from one chamber 5E, to the other. Une of the chambers 3l is provided at one end With an inlet port and the other chamber 3l is provided at its opposite end with an outlet port S3. Registeringr with port is an inlet structure El through which air may be driven hv means of a fan mounted on a stud shaft 3G and provided with a suitable driving" pulley 37A B v the ahove arrangement, the two chambers 3l are liept constantlyvlled with a moving current oic air which passes from one chamber to the other successively through the several valve ports 19 and, because of this action and he `anse the cooling air Currents comi` into direct Contact with the eX- ternal surface o't the valve, the valve is kept cool, the absorption of heat being directly from the valve hy the cooling medium, instead of through hearingr surfaces in the ordinary manner.

The valve will, of course, be connected by suitable gears 41 to he driven in proper timed relationship to the pistons of the engines.

The head l2' is perforated by an exhaust passage 42 and an inlet passage 43, which extend into the seat 17 in proper positions toy register with the port 19 when it registers with the ports 24 and 25, respectively.

The cylinder heads may he provided With passages 44 through which a cooling medium may hecirculated and may also he provided with an oil conduit 45 which opens into the seat l?.

lt will he noticed that by providing the movable cylinder head which also forms a for the rotary valve.. a closer association of the valve with its seat is obtained when the pressures are greater, but that at all times the seats are free to'he accommodated to variations in the valve. It is detures be incorporated int-o a single struc ture, bot-h for convenience in production and also to balance the pressure on the valve.

I claim as my invention:

l. In an engine, the combination with the cylinder, of a movable head mounted in said cylinder' and provided with a valve seat in.

its outer end, a rotary valve mounted in said seat, a second seat for said valve spaced f'rom'the first seat, and air circulation paissages flanking the valve between the two seats to directly cool the same.

In an engine, the combination with .the cylinder, of a movable head mounted in said cylinder' and provided with a valve seat in its outer end, a rotary valve mounted in said seat, a second seat for said valve spaced from the first seat, air passages fianking the valve between the two seats` and means for causing a circulation of air through said flanking passages and the ports-of the valve. 3. In an engine, the combination with a cylinder, 0f a .rotary valve controlling induction and eduction to said cylinder, and a pair of separated seats for saidyalve. and a casing structure inclosing sai'djvalvc between the seats to form a Flanking air circulation passage immediately adjacent the valve to directly cool the same.

4. In an engine, the combination with a cylinder, of a rotary valve controlling induction and eduction to said cylinder, and a pair of separated seats for said valve, a casing structure inclosing said valve between the seats to form a fianking air passage im inediately adjacent the valve, and means for causing a circulation of air through said flanking passage and the ports of the valve.

In witness whereof, I have hereunto set my hand at Indianapolis, Indiana, this 25th dayv of February, A. D. one thousand nine hundred and fifteen.
